Reexamining Python 3 Text I/O. Python 3.1’s IO performance is a huge improvement over 3.0, but still considerably slower than 2.6. It turns out it’s all to do with Python 3’s unicode support: When you read a file in to a string, you’re asking Python to decode the bytes in to UTF-8 (the new default encoding) at the same time. If you open the file in binary mode Python 3 will read raw bytes in to a bytestring instead, avoiding the conversion overhead and performing only 4% slower than the equivalent code in Python 2.6.4. # 28th January 2010, 1:28 pm
Current State of Unladen Swallow (Towards a Faster Python). The Unladen Swallow team are now planning to merge their work back in to the mainline Python 3 branch, adding a powerful incentive for Python developers to port their old Python 2 code (since the official Python 2.x line is extremely unlikely to have Unladen Swallow merged in to it). # 7th January 2010, 12:41 pm
